This European Standard specifies the requirements and test methods for the construction, the safety and the rational energy usage of an assembly made up of a boiler body complying with EN 303-11) and a forced draught gas burner complying with EN 676, using combustible gases, hereafter referred to as a “boiler??.
#This European Standard applies to standard boilers and low-temperature boilers with a nominal heat output not exceeding 1 000 kW and with a water temperature at normal operation not exceeding 105 °C.$
This European Standard does not contain all the necessary requirements for:
assemblies designed as units;
condensing boilers;
boilers intended to be installed in the open;
boilers permanently fitted with more than one flue outlet;
boilers fitted with a draught diverter;
boilers intended to be connected to a common flue having mechanical extraction.
This European Standard does not apply to living-space dedicated boilers (see 3.6).
If the boiler body has already been tested with a liquid fuel burner, in accordance with EN 303-1, EN 303-2 and EN 304, only the tests described in Annex G need to be performed.
In the case of a range of boilers, see Annex F.
